Review and Unit Quiz

This unit looked to present some of the basic processes found in the planetary boundary layer (PBL), including:

1. weather processes: focus on convective turbulence and gradient Richardson number
2. pollutant removal processes: included here were wet and dry deposition; chemical reaction processes; and pollutant dispersion
3. wet deposition: examples of wet deposition are acid rain and acid fog
4. dry deposition: dry deposition involves three stages: aerodynamic, surface, and transfer
5. chemical reactions: chemical reactions represent one type of removal process for pollutants in the PBL
6. evapotranspiration: the discussion in this reading was on the effect of moisture, partly controlled by evapotranspiration, on the height of the PBL
